BAND-CUTTING FEEDER FOR THRASHERS.

SPECIFICATION forming part of Letters Patent No. 233,959, dated November 2, 1880.

Application filed May 3, 1880.

To all whom it may concern Be it known that I, RIOHAR TflWORTH- INGTON, of Ohillicothe, in the county of Ross and State of Ohio, have invented a new and useful Improvement in BandOutting Feeder for Thrashing-h/Iachines, of which the following is a specification.

My invention relates to that class of machines which arespecially adapted for cutting the bands of sheaves, spreading the grain, and supplying the same to the thrasher, the band being separatedfrom the straw and discharged below the machine.

In the annexed drawings, making a part of this specification, Figure l is a plan View. Fig.2 is a side elevation. Fig. 3 is a longitudinal vertical section.

The same letters are employed in all the figures in the'indication of identicaljparts.

A is the frame of the machine, fitted at the outer end with folding legs A, by extending which proper inclination may be given to the feeder.

B B are endless belts, running around pulleys at the ends of the machine, and separated by a longitudinal bar, 13, which is slotted at B to permit the withdrawalof the band.

The belts run in the bottom of the trough G O, furnished with deflectors DED, attached on each side for the purpose of directing the sheaves, which are fed in longitudinally under the cutter E, which is preferably a circular saw with fine teeth.

The saw is hung on the rotating shaft F, and has fitted on each side convex hubs E E, which extend from the shaft nearly to the edge of the saw. These hubs are segments of a sphere, and are intended to spread the sheaf when the band is cut, and so loosen and detach the band that it may be readily seized by the teeth of the clearer, which project through the slot B The hubs E E have attached to their outer faces radial and curved cleats E which are intended to assist in carrying the straw forward when the band has been cut, and also, by their inclination, to force downward and outward the ends of the severed band, so as more completely to relax it to facilitate its engagement by the teeth of the clearer. This clearer is (No model.)

formed by an endless chain, G, running around sprocket-wheels H H, and formed with hooks G, intended to engage the severed bands and draw them down through the slot 13 I is a cylinder, formed with projecting arms 1, arranged to rotate with their points in such relation to the chain that they shall catch any band which may hang to the hooks G and detach the same.

The machinery is driven from the pulley K by a single belt, which extends down from the pulley K to a double pulley, L, beincrossed, thence down to a lower pulley, M, on the end of the cylinder-shaft I, thence up and around the pulley N on the end of the shaft I thence under the pulley L to thepulley K. Thus, by means of a single belt, I give operation to all parts of the machine.

I do not claim theinvention, broadly, of the carrying-belts, the cutter, the divider, or the clearer, for all these parts have been independently employed in other machines; but my cutting mechanism is distinguished from any before used in such machines in this: that the double-convex divider or spreader is attached to the sides of the cutter and serves to force apart the ends of the band the instant that it has been severed. The clearing mech anism is distinguished from what has been heretofore known in this, that it is made to act in engaging the band while the sheaf is being automatically carried forward, and is used in combination with the spreader, which forces the ends of the severed wire apart so as to facilitate itsj seizure by the teeth of the clearer.

What I claim as my invention, and desire to secure by Letters Patent, is-- 1. A cutter. revolving in the line of the carryingtrough and having convex hubs attached to its sides so as to perform, simultaneously, the operation of cutting and spread in g, substantially as set forth.

2. A rotary cutter placed in the line of the trough, having convex hubs attached to the sides of the cutter, and provided with cleats, substantially as set fort 3. In combination with the rotating cutter,

and convex spreader attached to the sides of the cutter, endless carrying-belts B B, and intermediate slotted bar B, and rotating clearer, have hereunto' set my hand and seal this 20th the points G of which are arranged to pass day of April, 1880.

through the slot and draw out the band while the ,sheafi is being automatically car- RICHARD TOWNSLEY WORTHDGNN' ried toward the thrasher, substantially as set WVitnesses:
